[0058] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0059] like Figure 5 As shown in the figure, this embodiment discloses a battery swapping station, which includes a battery compartment 220 and a battery swapping compartment 210. The battery compartment 220 is used to store batteries, and the battery swapping compartment 210 is used for an electric vehicle 211 to drive into and have its battery pack replaced. The battery swapping station includes a battery swapping device 100, which can move between a starting position and an ending position to transport and replace battery packs. The starting position is located within the battery compartment 220, and the ending position is located within the battery swapping compartment 210.

[0060] like Figures 1 to 4As shown, the battery replacing device 100 of the embodiment includes a battery replacing platform 101 for carrying a battery pack and a horizontal moving mechanism for moving the battery replacing platform 101 and the battery pack between a starting position and an ending position. In the embodiment, the horizontal moving mechanism is a traveling wheel 102 arranged at a side portion 103 of the battery replacing device 100. The battery replacing device 100 further includes a position sensor 1 for determining the position of the battery replacing device 100 during movement between the starting position and the ending position. By arranging the position sensor 1 on the battery replacing device 100, the specific position and state of the battery replacing device 100 can be known in real time during the movement of the battery replacing device 100, effectively avoiding the defect that the original position measuring mechanism is inaccurate and thus the real position cannot be determined when the battery replacing device 100 is stalled, such as slipping, affecting the normal work of the battery replacing device 100. The working stability of the battery replacing device 100 is ensured and the maintenance cost is reduced.

[0061] As shown in Figures 2 to 4 , the position sensor 1 is an optical sensor. The optical sensor determines the position of the battery replacing device 100 by irradiating a plurality of target points 201 arranged at different positions along the travel route of the battery replacing device 100 in the battery replacing station.

[0062] The target points 201 of the battery replacing station are arranged on the irradiation path of the position sensor 1 when the battery replacing device 100 moves, as shown in Figure 5 . Specifically, as shown in Figure 5 , the target points 201 are arranged on the battery rack 221 of the battery replacing device 100 and the door frame of the battery replacing station. These positions are located on the travel route of the battery replacing device 100 and are not easily blocked and are easy to mount.

[0063] By using the optical sensor, the specific position of the battery replacing device 100 in the battery replacing station can be determined by irradiating the structure of the battery replacing station using the optical sensor and using the structure of the battery replacing station itself as a reference. This is simple and convenient. By arranging the target points 201 at different positions in the battery replacing station, when the battery replacing device 100 travels from the starting position to the ending position, the position sensor 1 of the battery replacing device 100 will irradiate the target points 201 along the way in turn as the battery replacing device 100 moves. The arrangement positions of the target points 201 are determined in advance and are arranged according to the travel distance of the battery replacing device 100. Therefore, when the battery replacing device 100 irradiates a certain target point 201, it means that the battery replacing device 100 is located at the position corresponding to the target point 201. By this structure, the optical sensor only needs to select the simplest optical switch, which only needs to judge the presence or absence of an electrical signal without complex distance calculation to know the specific position of the battery replacing device 100 in the battery replacing station.

[0064] Specifically, the photoelectric sensor includes a sensor body 10, an emitting part 11 and a connecting plate 12, wherein the emitting part 11 is arranged on the sensor body 10, and the sensor body 10 is fixed through the connecting plate 12 and the battery replacing device 100. The connecting plate 12 includes a plate connecting part 121 and a plate bearing part 122, the plate bearing part 122 is used for bearing and fixing the sensor body 10, and the plate connecting part 121 is used for connecting and fixing with the battery replacing device 100.

[0065] The connecting plate 12 is a one-piece plate member which is bent to form, wherein the plate bearing part 122 is a U-shaped groove formed by bending at one end of the connecting plate 12, and the sensor body 10 is arranged in the U-shaped groove and fixed through a screw. The plate connecting part 121 is formed at the other end of the connecting plate 12, a waist hole is formed on the plate connecting part 121, a screw passes through the waist hole to connect with the battery replacing device 100, and the position of the position sensor 1 can be adjusted by adjusting the position of the screw in the waist hole. In addition, the plate connecting part 121 is bent to form an inclination angle between the plate bearing part 122, so that after installation, the plate bearing part 122 and the surface of the battery replacing device 100 have an inclination angle, which is convenient for alignment with the target point 201. In addition, the connecting plate is one-piece and easy to process, low in cost, high in strength and convenient to assemble.

[0066] As shown in Figure 3 , Figure 4 , the photoelectric sensor is inclined to the target point 201 in the battery replacing station. The photoelectric sensor is inclined to the target point 201, which is convenient for aligning the target and making the signal receiving more accurate. Specifically, the emitting part 11 of the photoelectric sensor extends outward from the sensor body 10 and extends towards the target point 201.

[0067] As shown in Figure 5 , the target point 201 also includes a deceleration point 202, when the photoelectric sensor irradiates the deceleration point 202, the battery replacing device 100 starts to decelerate. By setting the deceleration point 202, the battery replacing device 100 can decelerate in advance before reaching the end point, which is convenient for accurate positioning of the battery replacing device 100 and prevents the battery replacing device 100 from overshooting the end point due to untimely deceleration. In the embodiment, the deceleration point 202 is arranged on the door frame, which is located between the battery compartment 220 and the battery replacing compartment 210 and close to the end point.

[0068] As shown in Figure 3 , the position sensor 1 is arranged on the side part 103 of the battery replacing device 100. These positions can be arranged with the target point 201 without blocking the structure of the battery rack 221, the door frame and the like, and arranging the position sensor 1 at these positions can make the field of view open and not be blocked, so that the position judgment is more accurate. The position sensor 1 is arranged at a height higher than the horizontal moving mechanism. Avoiding the horizontal moving mechanism to block the photoelectric signal transmission, the position judgment effect is better.

[0069] In other embodiments, the back part of the battery replacing device 100 can also be provided.

[0070] As shown in the drawings, the battery replacing device 100 further comprises a position reaching sensor 2, which can detect whether the battery replacing device 100 is located at the starting position and the ending position. Figure 3 By providing the position reaching sensor 2, whether the battery replacing device 100 is located at the starting position and the ending position can be detected, and in combination with the position sensor 1, the position state of the battery replacing device 100 during the whole movement can be monitored, so that the operation of the battery replacing device 100 is more stable.

[0071] The battery replacing station further comprises a position reaching point, which is respectively arranged between the battery compartment 220 and the battery replacing compartment 210, and the position reaching sensor 2 of the battery replacing device 100 can detect whether the battery replacing device 100 is located at the position reaching point to determine whether it is located at the starting position and the ending position.
